If your traffic source is not expressly allowed in the affiliate program rules, please make sure you can use it in the program. For that, contact a Client Services Manager (if you have one) or submit a ticket to the support desk. Describe your traffic source in detail and request permission to use it. We will review your request and get back with a reply.
If your traffic source is not expressly approved, you should not use it: the advertiser may consider it a violation and decline the actions you generate.
